Prince Harry will reportedly not be happy with Prince William's latest move.
The Prince of Wales, famed patron of the Earthshot Prize, has added a close friend of Harry and his wife Meghan Markle as one of the members of his council.
William's move is said to make the Duke of Sussex 'jealous'.
Royal expert Phil Dampier told The Sun: “I'm sure Harry is probably a bit jealous because it looks like William has stolen one of his most important people.
“I think there will be some resentment.
“As I say, we don't know if they have had any disagreements, it could well be that José has managed to maintain friendship with both parties, he is a great guy who does a great job.
“But I wouldn't be surprised if Harry was a bit jealous, because other people have already seen a difficult situation between the two,” she said.
